ASNs issued today are subject to annual renewal. While this is a
small charge and doesn't go up based on the number of ASNs, so, not
100% effective at reclaiming all unused resources, it does, at least,
reclaim resources in use by defunct organizations that are no longer
paying the maintenance for them.
